This is an error code for the icemaker fan motor.
If the control does not see a signal coming back from the fan motor you will get this error code.
Please see the image below from the service manual that explains the ER IF error code.

The ER IF code indicates a failure of the icing fan.

You may notice slower ice production but the other fans should be okay.

You can select the ultra ice option and see if the fan toggles on.

The fan or the control is bad.

Check the door frame for a protruding small lever that gets pushed down when the door closes. If one is visible, that should be the light switch, which probably went bad and needs to be replaced. Without a model # hard to say how the light are set to go off, but most use the above method, hope this helps.

Here is a list of some things that can go wrong.

In addition, your drain tube maybe clogged

1. Defective heat coil
